Triaxys Wave Buoy and RD Instruments ADCP

Comparison of Directional Wave Parameters
Since July 2004 the author has been routinely measuring waves 10km offshore Savannah, Georgia, at a site with mean water depth of 13m, using a Triaxys wave buoy (see This report summarises a comparison of directional wave parameters from the buoy and 1,200kHz RD Instruments Acoustic Doppler Current Profiler (ADCP) equipped with pressure transducer and waves firmware. The ADCP was deployed beside the wave buoy, resulting in 72 days of comparative simultaneous hourly measurements of directional wave-energy spectra from the two systems. The goal of this report is to provide some results for objective comparison of the two instrument... (read more)

DANTE Buoy Controller System Delivers Live Data

The University of Washington (Seattle, USA) recently deployed an oceanographic observing buoy featuring Soundnine Inc.’s DANTE System. The DANTE controller collects data from a suite of meteorological and oceanographic instruments.  Two sensors are 60 feet underwater and use S9’s Ulti-modem inductive modem to communicate with the controller on the surface. The system forwards data by cellular modem to DANTE server (in the cloud), which delivers data in standardised format to NANOOS, a member of U.S. IOOS.   Data are available to the public in real-time through the NANOOS Visualization System (NVS) web app. The new buoy was deployed on 11 February...

ADCP Buoy and Float Manufacturing Relaunched

DeepWater Buoyancy, USA, has relaunched the oceanography/marine measurements line of syntactic foam ADCP buoys, StableMoor floats and trawl resistant bottom mounts (TRBMs) formerly manufactured by Flotation Technologies (Flotec). When Flotation Technologies’ parent company chose to discontinue the manufacture of this line of oceanographic flotation, DeepWater Buoyancy stepped in to take it over, continuing to supply flotation products to the oceanographic community. This month, the company is shipping StableMoor buoys, ADCP buoys and a wide range of cable floats and custom parts. DeepWater Buoyancy opened its doors on 1 January 2014 after securing the designs and manufacturing rights to the Flotation... (read more)

OSIL Installs Buoy Network in UAE

Ocean Scientific International Ltd. (OSIL) has installed a network of eight monitoring buoys off the coast of Abu Dhabi, UAE, in support of environmental monitoring. The rugged 1.2m coastal buoys are equipped with multiparameter sondes for water-quality monitoring plus GPRS telemetry equipment. The buoys are installed in water depths ranging from 6m to 16m, in various locations along the UAE coastline amid extensive coral formations and seagrass beds. The buoys are designed for extended deployment in harsh coastal environments in a range of water depths, and are extremely robust. The rotationally moulded PE hulls are foam filled to prevent the...

TRIAXYS Wave Buoy Supports Wave Energy

A TRIAXYS Directional wave buoy was recently deployed in 50 metre waters off the west coast of Norway. This buoy will support a major EU renewable energy company in their wave energy site assessments, with the eventual goal to provide marine energy plants along various locations off Norway's coast.     This buoy replaces a competitor's buoy and was chosen based on its ability to survive extreme weather conditions and high latitudes while using little power. The buoy uses VHF radio to send hourly data to an onshore receiving station. Users can also monitor the buoy's position and health online... (read more)

Polyethylene Tsunami Data Buoy for Japan

The data buoy, which has been in development for the past 3 years, is designed to detect potential tsunamis and warn the authorities by data transmitted ashore via radio and an Iridium satellite communication system. With a hull measuring 3.6m in diameter, the DB 16000 is the largest of the Mobilis data buoy range with an overall height of over 10m. The buoy’s hull is manufactured from multiple-section polyethylene floats and is the first PE buoy to be used for this sort of application. The buoy’s large hull supports an impressive marine grade aluminium tower, which provides a focal plane... (read more)

TRIAXYS Buoy to Assist at Wind Farm

Knowing the environmental conditions around a wind farm is crucial to a wind farm operator. Making wrong decisions from inaccurate or incomplete data can be costly in terms of time, money or even accidents. In an effort to ensure that it receives accurate and consistent wave and ocean current data, RWE Innogy (Germany) has invested in a TRIAXYS Directional wave and currents buoy. The German energy giant purchased this buoy after a careful, year-long review of available products on the market. It will deploy the buoy near its Nordsee Ost wind farm project. The buoy may then be redeployed at... (read more)

Oceanographic and Oil Spill Tracking Buoy

Fastwave (Australia) has commercially released the Voyager satellite tracking buoy, after an extended period of development and testing. The Voyager provides near-real-time ocean current, sea surface temperature and oil spill tracking data via Iridium satellite telemetry. The hull design and low freeboard ensures close coupling with the ocean surface layer and minimises wind influence, ensuring accurate tracking of the surface layer. The Voyager is simple to operate and deploy, making it suitable for oil spill response and search and rescue missions. It is also suitable for extended oceanographic studies, being capable of sending a report every four hours for up... (read more)

Wave Monitoring Buoy Deployed off Mauritius

Wave energy developer Carnegie Wave Energy Limited has successfully deployed and commissioned a wave monitoring buoy off the south coast of Mauritius. The project was carried out in conjunction with its Mauritian Project partners: The Mauritian Research Council (MRC), Australia’s High Commissioner to Mauritius and the University of Western Australia. This announcement follows Carnegie’s signing of a collaboration agreement with the Mauritius Research Council (MRC) to identify opportunities and develop pathways for commercial wave energy plants, for the republic of Mauritius, that are capable of providing a sustainable source of electrical power. Wave Energy Data Acquisition The purpose of this... (read more)
